We have dogs and I'm a pet sitter, so we have 2 different types of laminate in our house (in 2 different areas) because wood just isn't practical for us. Both have held up extremely well and have no scratches--one has been installed for 5 years, we have about 500 sq feet, and not one scratch. And here is why...
When I was choosing the laminate at Menards, I asked them if they had sample boards I could try to scratch. With both purchases, they had no issues with me trying to scratch a sample piece. If you take a car key and try to scratch them, you will find that some scratch very easily, and others not at all. One of the rooms we did was my craft room and I am rolling around in my craft chairs on that floor all the time (I swear I hardly stand up in there, I just roll from my shelf to my sewing table to the closet lol) and it has held up beautifully. Best part about it, it was only 78 cents per square foot! With the soundproofing roll, we spent under $200 to do that room and I kid you not, EVERYONE thinks it's real wood!
